Course Introduction：The tab-size attribute is used to control the number of spaces displayed by tab characters in HTML. The default is 8. The common usage is to adjust the indentation of the code block. 1. Basic usage: Set pre{tab-size:4;} to make the tab appear as 4 space widths, supporting numbers or inherit values. 2. Usage scenario: When displaying code in the structure, adjust the tab indent to make the layout more compact and beautiful, such as setting precode{tab-size:2;}. 3. Notes: Mainstream browsers support but IE is incompatible; it only affects tab display and does not affect spaces; child elements need to be set separately, otherwise the parent settings will not be inherited. The rational use of this attribute can improve the text display effect, especially for code document typesetting.

Course Introduction：The default VSCode theme path is not directly exposed, and built-in themes are usually integrated into the application. If installed through pacman, the home directory is /usr/share/code, but the theme file is not stored separately in the "themes" folder, but is compiled into the application or loaded at runtime. The themes installed by the user are located in the ~/.vscode/extensions/ directory. Each theme has an independent folder and contains a .vscode-theme file. To view the path of the currently used topic, you can observe the loaded file path when switching topics under the Network tab through the developer tool (Help>ToggleDeveloperTools). Summarize:

Course Introduction：The key to using one line of code to transition multiple attributes is to correctly use the abbreviation of transition attributes and pay attention to performance and compatibility. The specific methods are: 1. Use the all keyword to set the transition of all attributes uniformly, such as transition: all0.3sease; 2. Clearly list multiple attributes that need to be transitioned and set parameters separately, such as transition: background-color0.3sease, border-radius0.3sease; 3. Common application scenarios include button hovering effect, menu expansion/collapse and responsive layout switching; 4. Pay attention to avoid unnecessary attributes for transition, consider browser compatibility, and identifying them that cannot be passed.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
